I just snagged a CIB Japanese Marble Madness for my Mega Drive...
This version remains undumped and is much better than the EA's one. It's supposed to support the Sega Mouse to be used flipped upside-down as a track ball. I have the Japanese Sega Mouse and, finally, I'll be able to check the compatibility.
I don't have any dump device, but I'd like to dump it in order to preserve this memorable version (said to be almost arcade perfect) and share some Tengen awesomeness with all Genesis/Mega Drive lovers.
